The Miami Dolphins have seven days to decide if Pro Bowl cornerback Brent Grimes will get the franchise tag for the 2014 season. NFL teams have a two-week window that is closing on March 3. That provides the Dolphins one more week to negotiate with Grimes in an effort to reach a long-term extension. If both sides can’t agree, Miami is expected to use the franchise tag to prevent its No. 1 cornerback from hitting the open market as an unrestricted free agent.via - NFL Nation
